Offline mode for remote vault in the desktop client and mobile apps

[Novettam]

For those times when you don't have a network connection or your self-hosted vault is down... 😅.

Not sure what makes sense here. In the current paradigm, the client apps operate only on the remote server's vault files. Should the client, when connecting to a remote server, create/sync a local copy of the files and operate on a "local first" principle, syncing in real time with the sever if it is available to propagate changes to the server's copy and to other clients?

This probably makes things a bit more complicated. Keep the whole notes folder available offline? Only selected notes? Some kind of dynamic offline caching based on last accessed date with a setting to limit the max amount of local device space it can take, like some music streaming apps have? Keep some kind of search index available? etc..
